Dynastic terror is an attack on a head of state
or a ruling elite, precisely the kind of terrorist that the
international community tried to criminalize in the mid-nineteenth
century.

Focused Random
Terror

Focused random terror restricts the placing of
explosives, for example, to where significant agents of oppression
are likely to gather (as in the aforementioned case of the Polish
Underground)

Mass Terror

Mass terror is a terror by a state, in which the
regime coerces the opposition in the population, whether organized
or unorganized, sometimes in an institutionalized manner.

Random Terror

Random terror involves placing of explosives
where people gather (e.g. post offices, railroads, and cafes) to
destroy whoever happens to be there. "Algerian
revolutionaries left bombs in public places in Paris," one
scholar notes' "apparently convinced that one Frenchman blown
to bits was pretty much like any other."

Tactical Terror

Finally, tactical terror is directed solely
against the ruling government as part of a "broad
revolutionary strategic plan."
